Firefox 3.7 might have an Aero Glass supported theme in Vista and 7

Firefox 3.7 might have full support for Aero glass in Windows Vista and 7 as evident from some mockups available in the Mozilla Wiki. These are only mockups of what it might look like, but don’t raise your expectations to high. Mozilla had claimed to make Firefox 3 resemble the UI of different operating systems, but so far they didn’t get it right for Vista and XP despite many releases.

Here are the noticeable changes in the above mockup:

1. Embracing Glass: Toolbar and Tabs using Glass. Buttons translucent and slightly glossy to meld with the toolbar. Raised 3D look to achieve tactile “feel”.

2. Tools/Bookmark Bar: Connecting the Tools button to the side of the Window to emphasize the fact that it is used for customizing and changing the UI. Adding a button next to that to toggle the Bookmarks Bar which is turned off by default.

3. Page Button: Connect the Page button to the left side of the tab area. Directly connected to the Page
